Chelsea close in on £51m trio

Chelsea are reportedly close to sealing three new signings from Atletico Madrid. The club's interest in striker Diego Costa has long been known but Jose Mourinho is also said to be keen on defender Felipe Luis and midfielder Tiago.

But Southampton, who are searching for a replacement for Mauricio Pochettino after he resigned to take charge at Tottenham, say any deals will have to be on their terms - and need the approval of a new manager.

Chairman Ralph Krueger said: "It's very clear that we are in control of all the player transfers. All the top players are under long-term contracts.

"Any transfers that take place will be under our terms. We will decide the terms to potential transfers in and out of the club.

"We will involve the manager. That is important for everybody to know. We have been able to not agree to any transfers to date because we have control of the situation, and anybody who is saying anything else doesn't understand that we are in a strong position. We do not need to [sell anybody]."

Krueger's stance explains why the Shaw and Lallana transfers have appeared to stall. Liverpool made a bid of £20m for the midfielder but Southampton are said to want closer to £30m and interest from Chelsea in Shaw is likely to inflate the £25m fee United were said to be ready to pay.

But the chairman appears to be driving a hard bargain rather than ruling out player sales. When asked by the Southampton Daily Echo if the club would hold senior players who asked to leave to their contracts, Krueger said: "If transfers in either direction are in the best interest of the club, including all factors, then that's what we have to do.

"It will be in our mind as to what is best for the Saints and what is the best way for us to build a competitive team for August 16."
